WATCH-WINDING DEVICE.

Application filed December 31, 1&223. Serial 170.683,685.

tain new and useful Improvements in lfatch- Y VJin'ding Devices, of which the following is y a speciiication. y My invention relates to watch-winding devices, one object of the invention being the provisioiiot a device `which will insureV the rapid winding ot the watch in a very short time,v thus presenting a device which will prove very useful anddesirable in watch making` factories, by watch-repairers and others who iind it necessary to wind a large number of watches by hand.

Janother object of my invention is the production of a device ot' the character and for the purpose stated which can be produced at a price to make its use a necessity, which`v` will be of simple, strong and durable construction, which is designed to be used in connection with a watch repairers lathe, and which in all respects will be thoroughly etiicient and practical.

With these objects in View, my invention consists of a watch-winding device embody.

ing novel features of construction and combination of parts, substantially as described and defined by t-he claims and as shown in the accompanying drawing, in which:

Figure 1 represents a side view ol a watchwinding device constructed in accordance with and embodying my invention.

Figure 2 represents a vertical central sectional view o'f the device on a. line through the ball bearings. 4

Figure 3 represents a .sectional view of the pinions.

Figure t represents an inner face view of one of the rotary members of the device.

Figure 5 represents a view of the head or disk showing the gear wheels and ball bearings, and y Figure 6 represents a'view showing the manner of using the device in the winding of awatch.

Referring by numeral to the drawings in which the same numbers are used to indicate like parts in all the views of the drawing:

The device comprises a radial arm 1, to which is connected the shank or plate 2, formed with or connected to the disk or head 8, having a central opening e, and provided l disk 23, which is around one edge with ball bearings 5, the opening 4e receiving tlie'hub 6, formed on the liange disk 7, which is provided in its inner A flange with annular teeth 8.,A and formed in its outer iianged portion with interior threads 9, which engage the threaded vring 10, projecting inward from the disk 11, having` an inwarddisposed iiange 12, which with the rim oiE the disk 7, forms a pocket ,or chamber 13, to receive the elastic or yielding band 14.

Y Passing through the stud 6, and disc 11,

is the drive-shaft 16, formed with the threaded outer end 17, that carries the steel cone or circular cap 18, having an inclined periphery 19, which in connection withthe grooved ring 20, forms a ball track for the series of balls 21, the said grooved ring being seated in the cavity 22, of the flanged similar vin construction and the other flanged disk 7, and also has a hub 15 that tits within a socket in hub 6, and is also journaled on shatt 16. This ianged disk 23, is also provided with the annular set of teeth 24, sim# ilar to the other disk 7 and with the annular teeth 8 of disk 7, and the annular teeth 211 of the disk 23, mesh the gear wheels 8, and 23 of the disks 7 and 23 respectively, and said gear wheels mesh with the gear wheels 25 and 26, carried by the disk 3, as shown in Figure 5, the latter being connected to the disk 23, by a threaded of similar yielding ring 30, and when the watch stem is placed between the said soft or elastic rings the said rings rotating in opposite directions turn the stem 32, and naturally et'- fect the winding of the watch 33, this being shown most clearly in Fig. 6.

Where it is the custom to wind many watches much time may be saved by the einployment of this device whose shank 31 of the shaft 16 is adapted to be secured in the chuck of a lathe and the member 3 is held stationary by the arm 1 inakingf' Contact with the bed of the lathe so that the said member and its pinions remain in the same position while the device is being operated. As the shaft 16 rotates with the disc 11 motion is also given disc'27, but in an opposite direction, through the medium of the pinions 8, 25, 28 and 26.

The crown of the stem 32 may now be inserted between the yielding rings whose rotating irictional surfaces will rotate the forms ai twin to flange, and isv construction having a pocket or.

ico

crown and wind the watch as is commonly done by hand.

I claim:

l. In a watch winding device, the combination with revolving elements adapted to engage the erown of ay watch stem at each side, elastic facing on the opposing sides of said elements and a gear wheel carrying each element.

2. In a watch winding device, the combination with a head mounted on a handle, of a driving shaft, a gear wheel secured on the shaft, a gear wheel loosely mounted on the driving shaft, intermediate pinions adapted to cause the secured gear wheel to rotate the loose gear wheel, and frictional wheels adapted to engage the crown of a, watch stein and driven by the gear wheels.

3. In a watch winding device, in combination with a revolving element, a central stationary part having a handle, a pair of oppositely propelled members, one of which is connected to the revolving element, and both of which members engage the crown of the stem to effect the winding of the watch.

4. In a watch winding device the combination with a revolving element, a pairv of disks between which the stem crown is pressed, one of said disks through the drive shaft being connected to the revolving element, an elastic means carried by said moving or revolving members to bear against said stem crown to wind the watch.

5. A watch winding device consisting of a central stationary part; a pair of disks mounted at sides of one end of said central part, gearing connecting the central part and disks for effecting rotation of the said disks in opposite directions at about an equal ratel of speed, and means carried by said disks between which the crown is pressed to effect the winding of the watch.

6. A watch winding device consisting of a head carried by a handle, a shaft mounted in said head, discs mounted onthe shaft at each side of the head and having internal gear teeth, antifriction balls caged between the head and the discs, gear wheels mounted in the head and meshing at each side with the internal gear teeth, to cause rotation of the disks in opposite directions at equal speed, and a pair of revolving members carried by said disks and rotated thereby to turn the stein of a watch.

In testimony whereof I hereunto aiiiX my signature.

WILLIAM JOHN JACKSON.
